T0 (ir/ZZ whom, it may concern:

Beit known that I, LoUIs C. BAKER, a citizen of the United States,residing at 808 Sixteenth street, Parkersburg, in the county of Wood andState of West Virginia, have invented certain new and usefulImprovements in Molded Roof Collars and Flashings and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

For roof-pipes, such as soil or Ventilating or steam pipes, I havedesigned an improved adjustable collar and flashing and a ring forcalking said collar for forming water-tight connections with the roofand with the pipe passing therethrough; and my improvement resides inlead molded blank members each having an identical collar and flashingpart, so that in assembling them with the pipe each collar part can becut and shaped so as to change its original blank form from a horizontalroof to roofs of any angle or pitch and to form when assembled a collarof double walls around and in contact with the walls of the pipe,whereby each member is interlocked with the other in being fitted to thepipe. A lead calking-ring supplements the collar members and forms aclamp and a calk for securing and sealing the collar members at theirjoining with the pipe and at the meeting ends of the outer collar part.

In the accompanying drawings, Figure 1 shows in perspective the moldedcollar members as they are produced in separate blank parts each with aflashing for a horizontal The dotted lines show the cuts made toadaptthe collar to pitched roofs. Fig. 2 is a vertical section showingthe molded collar members and their flashings when the collar parts arecut and assembled on the pipe in a vertical position on a pitched roofand before the collar is calked by the ring to seal the pipe-joint. Fig.3 is a side view of the separate molded members and their flashings,showing thc manner of cutting the collars to adapt them to assume avertical position for a pitched roof. Fig. 4 shows the same inperspective. Fig. 5 shows in perspective the se arate collar parts andtheir flashings when fitted and locked one with the other when assembledon the pipe on a pitched roof. Fig. 6 shows in vertical section thecollar parts and their fastening and calking-ring assembled on the pipeand the collar-joints calked by the ring. Figs. 7 and 8 show the calkingand inclosing ring for the collars.

Looking at Fig. l is seen two identical collar-forming parts l, eachhaving an integral flashing 2, the collar parts being formed like theletter U and rising from the flashing constitute each a molded member ofthe collar and its flashing, the top edges of the collar parts beingparallel with the flashing. The blank members thus molded are adaptedfor horizontal roofs, but they can be changed for pitched roofs byremoving awedge-sh aped part 3 (shown by dotted lines) from each side ofone of the collar parts. This is done by a cut 4, extending from theedge of the flashing along the joining of this collar part with theflashing, and a out 5, exten ing from the edge of the collar obliquelyto the termination of the base-eut 4, as seen in said figure, such cutstermination being at about the joining of the straight collar part withthe curve'd part. This allows the undercut ends to be forced down toclose the cut-out and to be bent around to complete the circle of thecollar, as at 5 in Fig. 4, thereby making the collar vertical and theedge of the collar horizontal to the oblique flashing to suit the pitchof the roof. The edge of the collar of the companion member is cut downobliquely at 6, Fig. 4, around. its curved portion to conform to thehorizontal edge 5 of the other member, so that when assembled the collarpart of one member will be coiled within the coiled part of the othermember, thereby forming double walls to the collar and locking the twomembers together, with the edge of each collar part meeting even and inhorizontal relation to the oblique flashing.

Referring to Fig. 4, it will be understood that the ends'of the collarsof both members are undercut at 4, as described, so that the free endsof each collar part can be bent in ring form, as shown in Figs. 4 and 5.In this interlocking relation of the collar parts the flashing of onemember will lap with thc flashing of the other member, so that the cutof the flashing of one member will be within the collar and covered bythe flashing of the other member when the two are closed and sealedaround the pipe, the lead being beaten to effectually close the cut 6 atboth sides of the overlap. In this way the collar and the flashing partseach being molded as a single piece the collars can be undercut, asindicated by full and by dotted lines, to allow them to be bent on theirconnection with the flashing from the straight form shown in Fig. 1 tothe circular form shown in Fig. 5 to fit them around the walls of thepipe and to be adjusted to fit different sizes of pipes. In assemj blingthe collars one of them is first secured to the roof by its ashing andthe undercut ends of the collars are closely bent around the pipe Theother collar member is then slid over t e collar and flashing of thefixed collar member and bent around it and secured to the roof. While awater-tight joint is thus made by the flashing with the roof, the jointbetween the collars and the pipe is eX osed for leakage, because thepacking of the ead collar against the walls of the pipe will not make awatertight oint, as in Fig. 2. To seal this joint, I provide acalking-ring 8, of lead, which when fitted over the ends of the collarparts stands above their edges, as at 9 in Fig. 2, and while the ring isdriven tight upon the collar parts with a clamping function upon thepipe the projecting edge 9 of the ring is caused to form a calkingelement when beat over, as at 10, upon the edges of the collar membersand within thejoint between the latter and the walls of the pipe, as inFig. 6, thus sealing the collar-pipe joint. Referring to Fig. 1, it willbe understood that while the parts molded in blank, including theflashing of each collar part, are in the form adapted for horizontalroofs, each collar part at its open end is undercut at each side toseparate its ends from the flashing to allow them to be bent around ythe pipe, as indicated by dotted lines in Fig. 1, while maintaining thehorizontal relation of the edges of the collar with the roof.

In Fig. 3 at 1 1 is seen the cut and in dotted lines 12 is shown how thecollar is beat down on the ashing and closing the'cut to bring its topedge horizontal and its collar wall 13 vertical to fit the Verticalpipe. This advantage is due to molding the collar and the flashing partsin one piece, and it saves time, solder, and skilled labor in the workof applying the collar and its flashing. Different calkingrings aremolded for dierent sizes of collars and can be applied to any kind andform of roof.

I prefer to mold the ring with a depending skirt 14 of thin walls, sothat its lower edge can be trimmed off to suit the pitch of the roof andto form a tight joint with the flashing by beating thereon the edge ofthe skirt and serves to inclose and seal the joint at the meeting endsof the outside collar part, which would stand open more or less, as inFig. 5. The collars may be of any suitable projection or height from theflashing and the skirt part can be adapted for horizontal roofs andforms itself the calk for the top joint of the collars, a verticalclosure for the collars, and a seal around the collars at the flashing.
